嗨,我想展示一个加载轮,向用户显示数据正在加载,请坐着等待。为此,我必须使用serverSide: True
,然后发现它破坏了表的功能。
该表将不再仅在每页显示10个条目,而是显示所有条目,底部的数字告诉您有多少个条目将仅显示0。加载数据后所有这些都会发生。
这是DataTable的代码:
var visitorTable = $('#visitorTable').on('error.dt', flashToasts).DataTable({
serverSide: true,
order: [[ 3, "desc" ]],
processing: true,
language: {
processing: '<i class="fa fa-spinner fa-spin fa-3x fa-fw" style="margin-top: 100px"></i><span class="sr-only">Loading...</span> '
},
scrollX: true,
ajax: {
url: site.uri.public + '/api/list/visitors_basic_details/' + start + '/' + end,
dataSrc: function(json) {
$('#list_title').html(json.length + ' Visitors for the selected date range');
identities = json;
return json;
}
},
columns: [
{data: 'avatar_url',
"orderable": false,
render: function(data, type, full, meta) {
if(data != '') {
image = '<img src="' + data + '" alt="Profile Picture">';
} else {
if(full.gender == 1)
image = '<img src="' + site.uri.public + '/images/female-avatar.png" alt="Profile Picture" height="50px" width="50px">';
else if(full.gender == 0)
image = '<img src="' + site.uri.public + '/images/male-avatar.png" alt="Profile Picture" height="50px" width="50px">';
else
image = '<img src="' + site.uri.public + '/images/mixed-avatar.png" alt="Profile Picture" height="50px" width="50px">';
}
return image;
}
},
{data: 'first_name',
render: function(data, type, full, meta) {
if (full.gender != null) {
if(full.gender == 0) {
gender = 'Male';
} else {
gender = 'Female';
}
} else {
gender = '';
}
if (full.birth_date != null) {
age = Math.round(((new Date()).getTime()/1000 - full.birth_date) / (60 * 60 * 24 * 365));
} else {
age = '';
}
return '<font color="#E15910">' + data + ' ' + full.last_name + '</font>' + '<br>' + gender + ' ' + age;
// return (new Date()).getTime();
}
},
{data: 'email_address'},
{data: 'last_seen',
render: function(data, type, full, meta) {
if (data != null) {
last_seen = moment.unix(data).format("DD/MM/YYYY HH:mm");
} else {
last_seen = '';
}
// Hide the timestamp so you are able to sort the column correctly
return last_seen;
}
},
{data: 'provider',
render: function(data, type, full, meta) {
if (data == '') {
return 'Registration Form';
} else {
return capitalizeFirstLetter(data);
}
}
},
{data: 'marketing_consent',
render: function(data, type, full, meta) {
if (data == 1) {
return 'Yes';
} else {
return 'No';
}
}
}
]
});
下面是显示总数为0的示例:
这应该是这样的:
当我移除serverSide: True
时,它们又可以正常工作,但没有显示加载轮。
答案 0 :(得分:0)
请在Ajax调用中尝试这样
url: site.uri.public + '/api/list/visitors_basic_details?draw=1&start=' + start + '&length=' + end,
在服务器端,
public JsonResult visitors_basic_details(string draw, int start, int length)
{
}
注意:上面是一个MVC.Net服务器端示例,“ draw”需要类型转换为整数。
